Abstract
【選択図】なし
Description
したがって、本発明は、上記の水中油型乳化化粧料の調製方法にも関する。この方法は、成分(A)から(E)の混合物を、高圧ホモジナイザーにより、100MPa以上、好ましくは150MPa以上、より好ましくは200MPa以上、また、好ましくは500MPa以下の圧力で乳化するステップを含む。圧力は200MPaとすることができる。
調製方法の第1のステップでは、第1の混合物を得るために、水性媒体(A)、アニオン界面活性剤(B)及びポリマー(C)を温度Tで加熱し、混合し撹拌(例えば2500rpmの速度で)すればよい。
第2のステップでは、第1のステップで得られた第1の混合物に油剤(D)及び電荷中和剤(E)をこの順で加え、第1のステップと同じ条件で撹拌された第2の混合物を得ることができる。第2のステップにおける成分の混合及び添加は、好ましくは温度Tに等しい温度で行われる。
第3のステップでは、第2の混合物を温度Tから室温まで冷却した後、高圧ホモジナイザー(例えば、モデルStar Burst:スギノマシン社の製品)で乳化して、水中油型乳化化粧料を得る。圧力は、好ましくは100MPa以上、好ましくは150MPa以上、より好ましくは200MPa以上で、好ましくは500MPa以下である。圧力は200MPaとすることができる。
本発明はまた、上述した水中油型乳化化粧料を肌に施用するステップを含むスキンケアの方法に関する。スキンケアは、肌のナリシングを含み、これは、みずみずしく軽い感触、べたつきのなさ及び/又は肌への浸透感とともに好適に得ることができる。特定の実施形態では、本発明は、上述した水中油型乳化化粧料を肌に施用するステップを含む、肌のナリシング方法に関する。
表1に示す、含有するポリマーの種類及び含有量が異なる水中油型乳化化粧料は、以下の方法によりを調製された(実施例1〜9及び比較例1〜5)。まず、水性媒体(欄「a」)アニオン界面活性剤(欄「b」)及びポリマー(欄「c」)を加熱し、撹拌機を用いて2500rpmで混合し撹拌した。次に、油剤(欄「d」)、電荷中和剤(欄「e」)をこの順で添加して、成分を同条件にて混合し撹拌して、混合物を得た。混合物を室温まで冷却した後、高圧ホモジナイザー(Star Burst:スギノマシン社製)を用いて、200MPaの圧力で処理し、水中油型乳化化粧料を得た。各原料の含有量(質量%)は、表1に示すとおりである。
実施例1〜9及び比較例1〜5の水中油型乳化化粧料は、ナリシング効果、みずみずしく軽い感触、べたつきのなさ、肌への浸透感を、本発明者らが所属する組織の化粧品専門評価パネルによる肌への単回使用試験において評価され、評価は以下の基準で行われた。結果を表1に示す。
(1)ナリシング効果、みずみずしく軽い感触、肌への浸透感
A:強い
B:中程度
C:ほとんど感じない
D:感じない
(2)べたつきのなさ
A:べたつきを全く感じない
B:べたつきをほとんど感じない
C:べたつきをわずかに感じる
D:べたつきを感じる
実施例1〜9及び比較例1〜5の水中油型乳化化粧料について、変色の有無を評価した。調製した各水中油型乳化化粧料を透明容器に収容し、蓋で密閉して、自然光のもとで1か月保管した後に各水中油型乳化化粧料の変色の有無を評価した。評価は変色の少ない順にA〜Dの4段階で行われ、変色が全く認められなかったものをAとした。結果を表1に示す。
実施例1〜9及び比較例1〜5の水中油型乳化化粧料について、経時安定性を評価した。各化粧料を透明容器に収容し、蓋で密閉して、50℃で1か月保管した。保管後、油相と水相の分離を観察した。調製翌日および50℃で1か月保管後に、回転粘度計(Anton Paar GmbH製のRheolab QC)(回転数10rpm)を用いて、各化粧料のせん断粘度を25℃で測定した。油相と水相の分離の程度と、調製翌日から50℃での1か月保管までの粘度変化を観察し、初めの状態から変化の小さい順にA〜Dの4段階のスケールで評価した。結果を表1に示す。
実施例10〜12及び比較例6について、表2に示す、電荷中和剤の種類及び含有量が異なる水中油型乳化化粧料を、実施例1〜9、比較例1〜5と同様の方法により調製した。各原料の含有量(質量%)は、表2に示すとおりである。
実施例13〜16及び比較例7について、表3に示す、油剤及びノニオン界面活性剤の種類及び含有量が異なる水中油型乳化化粧料を、実施例1〜9、比較例1〜5と同様の方法により調製した。各原料の含有量(質量%)は、表3に示すとおりである。
実施例17について、表4に示す組成を有する水中油型乳化化粧料を、実施例1〜9、比較例1〜5と同様の方法により調製した。比較例8の水中油型乳化化粧料は、高圧ホモジナイザーによる高圧乳化を行わずに、攪拌機を用いて2500rpmで10分間撹拌しるのみにより得られた。各原料の含有量(質量%)は、表4に示すとおりである。
